theory contains a susce... | http://arxiv.org/abs/2308.08281v2 |
The image acquisition parameters (IAPs) used to create MRI scans are central
to defining the appearance of the images. Deep learning models trained on data
acquired using certain parameters might not generalize well to images acquired
with different parameters. Being able to recover such parameters directly from
an ima... | http://arxiv.org/abs/2303.04911v1 |
We study random walks on $\mathbb{Z}$ which have a linear (or almost linear)
drift towards 0 in a range around 0. This drift leads to a metastable Gaussian
distribution centered at zero. We give specific, fast growing, time windows
where we can explicitely bound the distance of the distribution of the walk to
an approp... | http://arxiv.org/abs/2307.07737v1 |
This paper presents a new approach for training two-stage object detection
ensemble models, more specifically, Faster R-CNN models to estimate
uncertainty. We propose training one Region Proposal Network(RPN) and multiple
Fast R-CNN prediction heads is all you need to build a robust deep ensemble
network for estimating... | http://arxiv.org/abs/2310.04829v3 |
Multiphase compressible flows are often characterized by a broad range of
space and time scales. Thus entailing large grids and small time steps,
simulations of these flows on CPU-based clusters can thus take several
wall-clock days. Offloading the compute kernels to GPUs appears attractive but
is memory-bound for stan... | http://arxiv.org/abs/2305.09163v2 |
We have proved new estimates for the coherent control errors of quantum
circuits used in quantum computing. These estimates essentially take into
account the commutator properties of the Hamiltonians and are based on the
formulas of the commutator calculus. | http://arxiv.org/abs/2307.08404v3 |
Recent advances in large language models have led to renewed interest in
natural language processing in healthcare using the free text of clinical
notes. One distinguishing characteristic of clinical notes is their long time
span over multiple long documents. The unique structure of clinical notes
creates a new design ... | http://arxiv.org/abs/2307.07051v1 |
We study the following problem: Can a collective of finite automata maintain
directed movement on a two-dimensional integer lattice of width 2, where the
elements (vertices) are anonymous? The automata do not distinguish between
vertices based on their coordinates of direction (that means each automaton has
no compass)... | http://arxiv.org/abs/2309.00292v1 |
Model-based component-wise gradient boosting is a popular tool for
data-driven variable selection. In order to improve its prediction and
selection qualities even further, several modifications of the original
algorithm have been developed, that mainly focus on different stopping
criteria, leaving the actual variable s... | http://arxiv.org/abs/2302.13822v1 |
In this paper, we introduce a tensor network (TN) scheme into the
entanglement augmentation process of the synergistic optimization framework by
Rudolph et al. [arXiv:2208.13673] to build its process systematically for
inhomogeneous systems. Our synergistic approach first embeds the variational
optimal solution of the ... | http://arxiv.org/abs/2305.06536v2 |
We present an update of the grid of detailed atmosphere models and
homogeneous synthetic spectra for hot, high-gravity subdwarf stars.
High-resolution spectra and synthetic photometry were calculated in the
wavelength range 1,000 \r{A} - 10,000 \r{A} using Non-LTE extensively
line-blanketed atmosphere structures. | http://arxiv.org/abs/2307.08362v1 |
Lexicographic Ranking SuperMartingale (LexRSM) is a probabilistic extension
of Lexicographic Ranking Function (LexRF), which is a widely accepted technique
for verifying program termination. In this paper, we are the first to propose
sound probabilistic extensions of LexRF with a weaker non-negativity condition,
called... | http://arxiv.org/abs/2304.11363v2 |
Second order stochastic optimizers allow parameter update step size and
direction to adapt to loss curvature, but have traditionally required too much
memory and compute for deep learning. Recently, Shampoo [Gupta et al., 2018]
introduced a Kronecker factored preconditioner to reduce these requirements: it
is used for ... | http://arxiv.org/abs/2305.19416v1 |
Deep neural networks (DNNs) have achieved remarkable success in a variety of
computer vision tasks, where massive labeled images are routinely required for
model optimization. Yet, the data collected from the open world are unavoidably
polluted by noise, which may significantly undermine the efficacy of the
learned mod... | http://arxiv.org/abs/2302.05098v1 |
Massively multilingual Transformers (MMTs), such as mBERT and XLM-R, are
widely used for cross-lingual transfer learning. While these are pretrained to
represent hundreds of languages, end users of NLP systems are often interested
only in individual languages. For such purposes, the MMTs' language coverage
makes them u... | http://arxiv.org/abs/2306.01709v1 |
